In principle, units of personality may be of two varieties: dimensional variables, which involve continuously distributed differences in degree, and class variables, which involve discretely distributed differences in kind. There exists, however, a prevailing and rarely questioned assumption that the units of personality are continuous dimensions and an accompanying prejudice against class vari...

A new mayfly species, Dipteromimus fiavipterus sp. nov., of the family Dipteromimidae is described on the basis of specimens of males, females and mature nymphs collected from Ofunato, lwate Prefecture, Japan. This new Dipteromimus species is characterized by a large body size, a yellowish body color (especially the frontal border of the forewings), short penis lobes, a slight elongation backwa...

The present study has attempted to explore the relationship among three Slovakian Haban populations with other Central European populations using finger ridge-count data. A multivariate approach to the analysis of finger-ridge count data allows for the study of population relationships using R-matrix calculations. Historical and ethnographic evidence suggests that the Haban populations have rem...

We have used eight pairs of simple sequence repeat (SSR) primers to analyse the genetic diversity in 130 individuals of coconut (Cocos nucifera L.) comprising 75 tall individuals and 55 dwarf individuals, representing 94 different coconut ecotypes throughout the world. A total of 51 alleles were detected, with an average of 6.4 alleles per locus. Fifty alleles were detected in tall coconuts (ta...

Two rapid spectroscopic approaches for whole-organism fingerprinting--pyrolysis mass spectrometry (PyMS) and Fourier transform infrared spectroscopy (FT-IR)--were used to analyse 22 production brewery Saccharomyces cerevisiae strains. Multivariate discriminant analysis of the spectral data was then performed to observe relationships between the 22 isolates. Upon visual inspection of the cluster...

Taxonomic and phylogenetic analyses of great apes and humans have identified two potential areas of conflict between molecular and morphological data: phylogenetic relationships among living species and differentiation of great ape subspecies. Here we address these problems by using morphometric data. Three-dimensional landmark data from the hominoid temporal bone effectively quantify the shape...

ABSTRACT.Seven of the 17 families of bats are represented on Madagascar, one of which, the Myzopodidae, is endemic to the island. Three genera, Pteropus, Emballonura and Mormopterus, occur in Madagascar and Asia but not in Africa. Two other genera found in Madagascar, Eidolon and Triaenops, do not occur in Asia but are found in Africa. Of the 28 species of Madagascar bats for which specimen rec...
